first embodiment

[0028]FIG. 2 is a diagram illustrating a WLAN service system using multiple channels in accordance with the present invention.

[0029]As shown in FIG. 2, the WLAN service system according to the present embodiment includes a wireless local area network (WLAN) service apparatus 201, first to third wireless terminals 202 to 204, and an access point 205. That is, the WLAN service apparatus 201, the first to third wireless terminals 202 to 204, and the access point 205 form one basic service set (BSS).

[0030]The service area of the access point 205 includes only the WLAN service apparatus 201. The WLAN service apparatus 201 according to the present embodiment is a wireless terminal. The WLAN service apparatus 201 request a WLAN service to the access point 205 and receives data from the access point 205.

[0031]The WLAN service apparatus 201 additionally transmits data from the access point 205 to the first to third wireless terminals 202 to 204 included in a service area of the WLAN service ...

second embodiment

[0034]FIG. 3 is a diagram illustrating a WLAN service using multiple channels in accordance with the present invention.

[0035]As shown in FIG. 3, the WLAN service system according to the present embodiment includes a wireless local area network (WLAN) service apparatus 301, first to third wireless terminals 202 to 204, and an access point 205.

[0036]Unlike the WLAN service apparatus of FIG. 2, the WLAN service apparatus 301 is an access point. The WLAN service apparatus 301 provides a WLAN service to the first to third wireless terminals 202 to 204 included in a service area of the WLAN service apparatus 301. Further, the WLAN service apparatus 301 transmits data transmitted from the access point 205 to the first to third wireless terminals 202 to 204 included in the service area of the WLAN service apparatus 301. That is, the WLAN service apparatus 301 according to the present embodiment operates as a wireless terminal in view of the access point 205 and operates as an access point i...

third embodiment

[0055]FIG. 7 is a diagram illustrating a WLAN service system using multiple channels in accordance with the present invention.

[0056]As shown in FIG. 7, the WLAN service system according to the present embodiment includes a WLAN service apparatus 701, first to fourth wireless terminals 702 to 705, and an access point 706. The WLAN service apparatus 701 of FIG. 7 additionally includes a mobile unit unlike the WLAN service apparatus 201 of FIG. 2. For example, the WLAN service apparatus 701 is included in a robot to additionally apply the mobility to the WLAN service apparatus 701 in FIG. 7.

[0057]The WLAN service apparatus 701 transfers data transmitted from the access point 706 to the first to the fourth wireless terminals 702 to 705 while traveling from an inside of a service area of the access point 706 to an outside of the service area of the access point 706. That is, the WLAN service apparatus 701 receives a service request from the first to fourth wireless terminals 702 to 705 a...

Abstract

Provided are an apparatus and method for providing a WLAN service using multiple channels. The wireless local area network (WLAN) service apparatus includes a service request receiver configured to receive service request information from a first wireless terminal accessed through a first channel, a data receiver configured to receive data from a first access point accessed through a second channel according to the service request information, a data transmitter configured to transmit the data to the first wireless terminal in a predetermined service area, and an access controller configured to control the first wireless terminal and the first access point to be accessed through different channels.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an apparatus and method for providing a wireless local area network (WLAN) service and more particularly to an apparatus and method for providing a WLAN service using multiple channels.[0003]2. Description of Related Art[0004]Lately Internet population has been continuously increased. Particularly, many users use a wireless local area network (WLAN) for the Internet. A WLAN service is to provide typical services, which were used to be provided by a wired LAN service, using wireless medium for transferring data. In general, IEEE 802.11 infra-structure has been used as a wireless communication method.[0005]The WLAN service enables a wireless terminal which called station (STA) to receive various services including a wireless Internet service using an access point (AP) as a wired / wireless gateway. For example, The wireless terminal may be apparatus such as a notebook computer or a personal ...
